More likely, it inverts the channel entirely, and then "re-inverts" the signal simply by reversing the colour coding of the speaker binding posts on that channel. This does cause the two channels to load the power supply primarily out-of-phase, allowing the use of a smaller power supply for the same output power (clever) and also means that bridging the amp for mono requires nothing more than connecting both channels' inputs together. Unfortunately, it must mean that the amp is incompatible with headphones or anything else that requires a common speaker ground.
